A representative of the production company, Samhwa Networks, revealed to news outlet MBN, “We have been notified that Kim Jung Eun and Kim Su Ro have left the drama. This is confusing as not much is left until the drama goes into production. We are forced to have a new casting session as soon as possible.”

The drama has been gaining interest for marking the two actors’ return after a three-year absence from the small screen. Kim Jung Eun and Kim Su Ro were expected to portray the main couple, but due to both lead stars dropping out of the drama, the sudden setback is likely to affect the production schedule.

“My Heart Twinkle Twinkle” tells the success story of two families that run fried chicken restaurants, and it is expected to premiere in January after “Birth of a Beauty” ends its run.
